Feature Focus: Windows Intel HW Decode performance improvement for H264/HEVC

[Brajesh]

We have improved Decode performance on Intel  Windows machine for H264 and HEVC. 

You should see improved playback, seek and scrub performance on Beta builds. Reverse playback performance is also improved.

Make sure HW preference to enable this feature is enabled. It is supposed to be enabled by default.

Steps to enable Hardware-accelerated Decoding:

• Navigate to Preferences > Media 
• Select Enable hardware accelerated decoding (requires restart)
• Restart Adobe Premiere Pro

Refer to this page for Intel HW decode system requirement.

Please try out and let us know how it is working on latest Beta builds.

Thanks

Please please please put some time into fixing the H.264 LongGOP decoding FramePrefetchLatency bug DVAFM-1026 I’ve given Mitch and Bruce more sample footage than they want it happens in Software Only and with HW accelerated decode

What cameras are you seeing this on in the community, John? Drone footage?

DJI drone footage mostly, also ABC Newsone wire footage (not CNN notably), my personal dashcam does it

Seems to be a large number of consecutive P frames with no B frames that freaks it out. Clearing the Media Cache alleviates the issue temproarily. You'll see high CPU and disk usage for a while after you stop playback in Premiere too. 

We've seen great advancements in VFR performance in the latest versions so kudos for that, sometimes Premiere handles it better than even FFMPEG, but DJI footage cut better in 2018 than it does in current versions and that's undoutably a bug.

any progress on H264 hardware accelerated decoding support for nvidia cards?
